883 883  If Opis is running typically on the the averaged data is saved. For several experiments it may make sense to save the information for each single bunch. This is up to now done by saving the complete ADC trace of the TOF setup. This is a huge amount of data and needs processing. This has to be performed after the beamtime in close contact to [[Markus Braune>>mailto:markus.braune@desy.de||shape="rect"]] ( responsible for [[OPIS>>url:http://photon-science.desy.de/facilities/flash/photon_diagnostics/opis_spectrometer/index_eng.html||shape="rect"]])
